' A COR-PORATIGN OF NEW YORK METHOD OF MAKING LINOLEUM Application filed August 11, 1930. Serial No. 474,404.

The present invention relates to the manuthe other primary sheets or series of sheets. facture of linoleum and more particularly to Preferably, but not necessarily, each sheet is the manufacture of sheets of linoleum commono-colored. Thus, the primary sheets A position or the like in which variously colored and likewise the composition A from which 5 linoleum composition is combined to produce they are formed may be of a light green color, 55 a variegated appearance. primary sheets B and the composition B a The chief object of the invention is to profrom which they are formed may be of a vide a novel method of producing, from plasdark green color, and primary sheets C and tie material, a sheet of continuous indefinite the composition C from which they are length having a uniform Variegated effect formed may be of an intermediate shade or 60 from end to end, and adapted to be employed color of green. 111 some cases, one or more in the well-known automatic mlaymg maseries of primary sheets may be variegated,

chines of the Valton or Batten type. particularly where such sheets are formed Broadly, the method of my invention comfrom reject composition as hereinafter deprises forming a plurality of series of dilferscribed. o6 ently colored primary sheets of linoleum com- The differently colored primary sheets of position or the like, the primary sheets ofthe respective series formed as above deeach series being of the same coloring but difscribed are next positioned in superimposed fering from the coloring of the primary overlapping relation to provide a continuous sheets of another series; positioning in preindefinite succession of overlapped sheets. determined order, primary sheets selected Preferably, one sheet from each series is arfrom the respective series, in superimposed ranged in predetermined order with sheets overlapping relation; maintaining a continuselected from each of the other series and the ous supply of said overlapping primary arrangement repeated indefinitely. The sheets; and consolidating the overlapping overlapping relation of the successive sheets primary sheets to form a continuous varieis such that only a narrow marginal edge of gated sheet. each sheet is exposed-for example-one to In the drawing 1 have illustrated diagramtwo inches. This necessitates the formation matically the manner of carrying out the inof primary sheets of relatively thin gauge 30 vention and I will now describe in detail the in order that the pile of overlapped sheets preferred method. will not be excessively thick and may be satis- Primary sheets A, B, and C are first formed factorily calendered. The continuous series from plastic linoleum compositions A, B, of overlapped primary sheets thus provided and C by means of a plurality of pairs of calis then consolidated by means of a pair of ender rolls aa, bb and 0-0. s procalender rolls (Z-(Z to form a single conduced, each primary sheet is of continuous tinuous variegated sheet D of reduced thickindefinite length, being subsequently severed ness. into units of predetermined size to provide a The composite sheet D may be applied in continuous succession of individual primary continuous lengths to a suitable backing such 40 sheets. One dimension of the unit sheet will as burlap, saturated felt or the like. Usually, 9t approximate the width of the final composite however, it will be employed with other sheet to be produced, while the other dimensheets of plain or variegated color in the sion is selected to provide a unit sheet which formation of block inlaid linoleum by means may be readily manipulated. Thus, where of the well-known automatic inlaying mathe final sheet is approximately six feet in chines of the WValton or Batten type. Vhen width, the unit primary sheet may be 6 employed in the latter manner, the rejected feet by 3 feet. blocks of the variegated sheet, resulting from Each primary sheet or series of succesthe inlaying process, may be re-used for the sive individual primary sheets is of uniformation of additional primary sheet maform coloring distinct from the coloring of terial for one or more of the series of primary sheets above described. In re-using the rejected blocks, the variegated composition is preferably treated so as to blend the several colors into a single shade thus providing mono-colored composition for the formation of one of the series of primary sheets. if desired, however, the rejected blocks may be formed into primary sheets without so blending the colors, in which event a series of variegated 1. *imary sheets will result.

Having disclosed my invention, it will be obvious to those skilled in the art, that numerous variations may be made in the manner of selecting and arranging the primary sheets of the respective es, to give a variety of pleasing artistic etl ects in the liual composite sheet, and I do not wish to limit my invention except as defined in the appended claims.

Claims:

1. The method of producing from plastic material, a sheet or continuous indefinite length, having a substantially uniform variegated eliect from end to end, which comprises the steps of forming a plurality of series o'l' dillerently colored primary sheets of plastic composition, the primary SllLc s of each series being of the same coloring but differing from the coloring of the primary sheets of another series: positioning, in predetermined order and in superimposed overlapping relation, primary sheets selected from the respective series to term a laminated sheet oi a thickness substantially greater than that intended for the finished product and of continuous indefinite length; maintaining a continuous supply of said overlapping primary sheets:

,and consolidating the overlapping primary sheets to form a variegated sheet of reduced thickness and or? continuous indefinite length.

2. The method of producing a sheet of linoleum of continuous indefinite length, having a substantially uniform variegated ell ect from end to end, which comprises the steps of forming a plurality of series of difit'erently colored primary sheets of linoleum composition or the like, the primary sheets of each series being of the same coloring but differing from the coloring of the primary sheetsot another series; positioning, in predetermined orderand in superimposed overlapping relation, primary sheets selected from the respective series to form a laminated sheet of a thickness substantially greater than that intended for the finished product and of continuous indefinite length; maintaining a. continuous supply of said overlapping primary sheets; and consolidating the overlapping primary sheets to form a variegated sheet of reduced thickness and of continuous indefinite length.

3. The method of producing a sheet of linoleum of continuous indefinite length, having a substantially uniform variegated effect from end to end, which comprises the steps of forming a plurality of series of diffcrcntly colored primary sheets of linoleum composition or the like, the primary sheets of each series being of the same coloring but differing from the coloring of the primary sheets of another series and the sheets of at least one of said series being variegated; positioning, in prmletermined order and in superimposed overlapping relation, primary sheets selected from the respective series to form a. laminated. sheet of a thickness substantially gr *ater than that intended for the finished product and of continuous indefinite length; maintaining a. continuous supply oi. said overlapping primary sheets; and consolid ating the overlappim primary sheets to form a variegated sheet or reduced thickness and of continuous indefinite length.

4. The method of noducing a sheet of having a substantially uniform variegated l t from end to end, which comprises the steps oi lj'orming a plurality of series of dillercntly colored primary sheets of linoleum composition or the like, the primary sheets oi each series being of the same coloring but dii'l ering from the coloring of the primary sheets of ani'rther series and the sheets ot certain series being mono-colored and the sheets of certain other series being variegated; positioning, in predetermined order and in superimposed overlapping relation, primary sheets selected from the respective series to form a laminated sheet of a thickness substantially greater than that intended for the finished product and ot continuous indefinite length; maintaining a continuous supply of said overlapping primary sheets; and consolidating the overlapping primary sheets to form a ariegated sheet of I'CdHCOtl thickness and of continuous indefinite length. In testimony whereof, I allix my signature.
